CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. §119 from U.S. Provisional Patent Application No. 60/845,656 titled “MODULAR FOOD SERVICE SYSTEM AND METHOD” filed Sep. 19, 2006 (Attorney Docket No. 071045-0146), the full disclosure of which is hereby incorporated herein by reference.

BACKGROUND

The present application relates to a modular service system. More specifically, the present application relates to a link or coupling member for connecting sectional units of a modular food service system.

It is generally known to provide food service systems. Such known food service systems typically include multiple sectionals or units that are connected together by fasteners, brackets, or the like. However, such known systems has several disadvantages including substantial effort needed to precisely align the units for assembly/attachment, as well as substantial effort needed to reconfigure or separate the units due to the fasteners and brackets used. As such, breaking down the system to reconfigure, store, or relocate it is a difficult activity. As such, multiple systems or customized systems are purchased and installed at a greater expense than if a single system could be quickly and easily assembled, disassembled, reconfigured, stored, relocated, or the like.

Accordingly, it would be advantageous to provide a modular service system that is readily, quickly, and easily assembled, disassembled, configured, reconfigured, or the like. It would also be advantageous to provide a link or coupling member for connecting sectional units of a modular food service system. It would further be advantageous to provide a connector link that assists in aligning and coupling the adjacent units and reduces or minimizes the effort required to install. It would be desirable to provide for a modular service system having one or more of these or other advantageous features. To provide an inexpensive, reliable, and widely adaptable link or coupling member for connecting sectional units of a modular food service system that avoids the above-referenced and other problems would represent a significant advance in the art.

Modular food service system 10 includes a first unit 12, a second unit 14, and a connector 16 coupling first unit 12 and second unit 14. Connector 16 is removable so that units 12, 14 may be reconfigured, relocated, or the like. System 10 is shown for use with a food service environment, but a person having ordinary skill in the art would recognize that the units and connector may be used in any of a variety of non-food service environments where it is desirable to have a modular arrangement. Also, system 10 is shown as having two sectional units, but a person having ordinary skill in the art would recognize that any number of sectional units may be used and coupled together by connectors in any of a variety of configurations.

Units 12, 14 (e.g., sectionals, stations, etc.) each include a base 18 and other features or components described further below and/or shown in the FIGURES. Base 18 includes a frame 20 and a plurality of panels 21. Frame 20 provides structural support for units 12, 14 and includes a plurality of vertical support members 22 and a plurality of horizontal support members 24. According to an exemplary embodiment, four vertical members 22 are located at corners of base 18 and are coupled at their ends by eight horizontal members 24. Vertical members 22 and/or horizontal members 24 are preferably tubes with a square cross-section. Alternatively, the members may have other cross-sections (e.g., circular, rectangular, etc.), may be solid, hollow, or the like.

Panels 21 are coupled to frame 20 to provide a barrier to inhibit access (e.g., visual, physical, etc.) to the inside area or space of base 18, to provide contamination protection to/from the space, and to provide a decorative outer surface to units 12, 14. According to a preferred embodiment, panels 21 are quickly and easily removable so that the unit may be coupled to another unit by another connector 16. Alternatively, panels may be coupled to frame 20 by any of a variety of techniques (e.g., fasteners, welding, hooks, etc.). A removable panel 25 is positioned on and supported by horizontal frame members 24 to provide a removable under-shelf.

Unit 12 further includes a top 26, a panel 28, a tray slide or shelf 30, and a kick-plate 31. According to an exemplary embodiment, top 26 (e.g., counter top, etc.) is quickly and easily removable from base 18 (e.g., to provide access to base 18, replace, clean, reconfigure, move, modular functionality, etc.). According to a preferred embodiment, top 26 is set on top of base 18 and supported by frame 20. Top 26 is secured or retained in place by down-turned edges on top 26 extending around the upper portion of base 18 combined with the weight of top 26 to inhibit movement except for intended movement. To remove, replace, clean, reconfigure, etc. top 26, one or more persons lifts top 26 from base 18 without having to remove or disconnect fasteners or the like. Panel 28 covers an opening and is removable to provide space/access to controls if unit 12 is to be converted to a hot food unit. Shelf 30 is movable on hinges and include members connected to shelf 30 by hinges and that slide into engagement with receptacles on base to also provide quick and easy removal from base 18. Kick plates 31 are coupled to base 18.

Receptacles 32 may be filled with water to heat the food pans (e.g., with steam) or ice to cool the food pans. Controls 34 are for controlling the temperature of receptacles 32 or other operation of unit 14. Shield 36 is coupled to top 26 and is configured to provide a barrier between people and food located in receptacles 32.

Referring to FIGS. 4-6 and 8, connector 16 (e.g., link, coupler, etc.) couples unit 12 to unit 14 in a secure and tight connection that minimizes or eliminates any space or gap between unit 12 (e.g., base 18 and/or top 26, etc. of unit 12) and unit 14 (e.g., base 18 and/or top 26, etc. of unit 14). Connector 16 includes an upper track 40, a lower track 42, a rear support member 44, a front support member 46, and a face plate 48. The secure and tight connection of unit 12 and unit 14 is provided by an engagement of upper track 40 with adjacent projections 58 and with lower track 42 adjacent projections 72 extending from base 18 of unit 12 and base 18 of unit 14.

Referring to FIGS. 4, 7, and 10, upper track 40 includes a horizontal base member 50, a pair of spaced apart vertical members 52 extending upwardly from base member 50, and a pair of spaced apart, inwardly disposed, opposed (opposing, opposite, etc.) horizontal engagement members 54 extending from spaced apart vertical members 52. Members 50, 52, 54 may be a panel, plate, portion, flange, or the like. A first (back, rearward, etc.) end of upper track 40 is coupled to an upper end of rear support member 44, and a second (front, forward, etc.) end is coupled to an upper end of front support member 46. Engagement members 54 define a slot 56 (e.g., gap, opening, space, etc.) that is configured to receive a projection 58 extending from an upper portion of frame 20 on unit 12 and an adjacent projection 58 extending from an upper portion of frame 20 on unit 14. Along a substantial length of slot 56, the spacing between an inner edge of engagement members 54 is generally constant. According to a preferred embodiment, the spacing between engagement members 54 (i.e., width of slot 56) is between about ⅛ inches and about ½0 inches. According to a particularly preferred embodiment, the spacing is about 1/4 inches. The spacing of slot 56 and the distance between projections 58 is designed to eliminate or minimize any gap between tops 26 of units 12, 14 by pulling projections 58 into a closely adjacent position (e.g., squeezing, compressing, pinching, etc.). At the second end of upper track 40, slot 56 widens to form an engagement guide 62 (e.g., funnel, catch, etc.) that is intended to facilitate and/or guide the engagement (e.g., coupling, connecting, receiving, etc.) with projection 58 on units 12, 14. According to an exemplary embodiment, engagement guide 62 is provided by edges of engagement members 54 provided by an angled cut-out that forms a triangular or “V” shaped portion of slot 56. According to a preferred embodiment showing FIGS. 7 and 10, edges 63 of engagement guide 62 extends at an angle a between about 10 degrees and about 45 degrees relative to slot 56. According to a particularly preferred embodiment, edges of engagement guide 62 extends at an angle a at about 30 degrees relative to slot 56. According to alternative embodiments, the engagement guide may extend at any of a variety of angles relative to the slot. Alternatively, the engagement guide may be provided by any of a variety of shaped openings (e.g., curved, other angles, etc.). According to an exemplary embodiment, projections 58 are generally downwardly extending vertical members of a U-shaped channel where the other spaced apart vertical member is coupled to upper portions (e.g., horizontal members 24) of frame 20 of unit 12 and of frame 20 of unit 14. Alternatively, projections 58 may be angled for the desired alignment and engagement.

Referring to FIGS. 4, 8, and 11, lower track 42 includes a horizontal base member 64, a pair of spaced apart vertical members 66 extending downwardly from base member 64, and a pair of spaced apart, inwardly disposed, opposed horizontal engagement members 68 extending from spaced apart vertical members 66. A first (back) end of lower track 42 is coupled to a lower end of rear support member 44, and a second (front) end is coupled to a lower end of front support member 46. Engagement members 68 define a slot 70 that is configured to receive projections 72 extending from a lower portion of frames 20 of units 12, 14. Along a substantial length of slot 70, the spacing between engagement members 68 is generally constant. According to a preferred embodiment, the spacing between engagement members 68 is configured and designed comparable to spacing of slot 56, and is designed to eliminate or minimize any gap between tops 26 and the bottom portion of units 12, 14 by pulling projections 72 into a closely adjacent position. At the second end of lower track 42, slot 70 widens to form an engagement guide 74 that is intended to facilitate and/or guide the engagement with lower projection 72 on units 12, 14. According to a preferred embodiment, engagement guide 74 is provided comparable to engagement guide 62 as described for upper track 40 (e.g., triangular or “V” shaped portion of slot 70). According to an exemplary embodiment, projections 72 are generally upwardly extending vertical members of a U-shaped channel where the other spaced apart vertical member is coupled to frame 20 of unit 12 and frame 20 of unit 14.

According to a preferred embodiment, projections 58 and 72 are located at both ends of units 12, 14 allowing as many units to be coupled together as needed or desired.

As such, the projections 58, 72 at the outer ends of system 10 (or both ends of a single unit) receive panels 21. Projections 58, 72 therefore are used to both engage connector 16 when coupling a pair of units 12, 14, and to receive panels 21 to close off ends of system 10. Panels 21 are quickly and easily removable for reconfiguration of system 10 (e.g., coupling another unti).

Referring to FIGS. 4-6, rear support member 44 and front support member 46 each includes a base member 86 and a pair of spaced apart side members 87 extending from ends of base member 86. According to a preferred embodiment, support members 44, 46 are formed by a stamp and bending operation to form U-shaped channels. According to alternative embodiments, the front and rear support members may have any of a variety of shapes or configurations that provide the desirable structural support.

According to an exemplary embodiment shown in FIGS. 3 and 4, an opening 88 is provided in connector 16 to allow utilities (e.g., electrical wiring, plumbing, etc.) to pass between unit 12 and unit 14. Opening 88 may be provided by a hole or aperture in a panel that is disposed between upper track 40, lower track 42, rear support member 44, and front support member 46. (The panel may also be provided without apertures to inhibit access between the units.) According to a preferred embodiment, connector 16 does not include such a panel and opening 88 is defined by inner surfaces of base members 86 of upper track 40, base members 86 of rear support member 44, and base members 86 of front support member 46. Opening 88 may also be provided with a support member to provide additional strength and rigidity (particularly when being inserted or removed) as shown in FIGS. 14 and 15 and further discussed below.

Referring to FIGS. 4-6 and 10, face plate 48 (e.g., front plate, panel, etc.) is intended to provide functional purpose and a decorative or ornamental purpose. As for the functional purpose face plate 48 is configured to limit the travel/movement of connector 16 so that connector 16 is in a last and predetermined position when engaged. Face plate 48 is also configured to engage frames 20 of units 12, 14 by at least partially wrapping around vertical members 22. Face plate 48 includes a base panel 90, flanges 92, and flanges 94. Flanges 92, 94 extend generally perpendicular to base panel 90. Face plate 48 is further configured to provide a user interface (e.g., handle, grip, etc.) for the user to grasp connector 16. As for the ornamental purpose, face plate 48 is configured to provide a continuous surface as visible to a person viewing system 10 both along the outside surface of system 10 and on an inside surfaces of frames 20 (e.g., by flanges 92, 94 wrapping around vertical members 22).

Referring to FIGS. 1-3, 7, 9, and 10, to assemble system 10, unit 12 is positioned (located, disposed, etc.) next to (proximate) unit 14 so that upper projection 58 and lower projection 72 on unit 12 are adjacent to upper projection 58 and lower projection 72 on unit 14. Connector 16 is then positioned so that upper and lower projections 58, 72 are aligned (registered) with engagement guides 62, 74 and slots 56, 70. Connector 16 is then moved in to bases 18 of units 12, 14 so that projections 58, 72 slide through engagement guides 62, 74 and into slots 56, 70. If projections 58, 72, are slightly separated or are not sufficiently closely aligned, engagement guides 62, 74 will move/guide projections into proper or better position and alignment (i.e., together towards a closely adjacent position as connector 16 is slid into units 12, 14). Connector 16 is further moved into engagement as projections 58, 72 slide through slots 56, 70 and until face plate 48 abuts vertical members 22 and is generally in planar alignment with the front surfaces of bases 18 of units 12, 14.

To disassembly system 10, a person grasps front plate 48 and pulls connector 16 out from bases 18 of units 12, 14.

FIGS. 12 and 13 are alternative embodiments for the engagement of connector 16 with upper track 40 and lower track 42. A friction reduction member is provided to reduce the friction between projections 56, 72 and interior edges of engagement members 54, 68 (which define slots 56, 70, respectively). Reducing the friction is intended to reduce the effort need to insert or remove the connector.

Referring to FIG. 12, a friction reduction member 100 is shown as an “L”-shaped member. According to an exemplary embodiment, member 100 is coupled (e.g., bonded or joined by adhesive, tape, fastener, etc.) to the U-shaped channels that provide projections 56, 72. Alternatively, member 100 may be in the form of strip of flexible material bonded to the “U”-shaped channel (e.g., tape with an adhesive such as a pressure sensitive adhesive). The tape may be applied to the “U”-shaped channel before or after it is shaped (stamped, bent, etc.) into the desired configuration (shown as a “U” shape). The friction reduction member may be made from any of a variety of materials that provide friction reduction properties. For example, an extruded or molded polymer such as an acetal resin (e.g., Dupont Delrin), a thermoset (e.g., Bakelite), nylon, a rubber (e.g., Sani-Tuff), or any of a variety of thermoplastics or thermosets. The member 100 may be treated to have low friction properties (e.g., TEFLON or other low friction treatments applied to a tape or other base).

Referring to FIG. 13, a friction reduction member 102 is shown according to an alternative embodiment. Member 102 is coupled to engagement members 54, 68. Member 102 may be a flexible sheet or member that is wrapped and adhered or bonded to interior edges of engagement members 54, 68 (e.g., a tape with an adhesive). Alternatively, members are extrusions (e.g., “U”-shaped) that are slid onto engagement members 54, 68 and held in place by an adhesive, tape, fastener, pressure (e.g., an interference fit between channel and width of engagement members 54, 68), or the like. Member 102 may be coupled before or after the upper and lower tracks are formed.

FIGS. 14 and 15 show alternative embodiments for connector 16 that are configured to provide additional strength and rigidity to connector 16, particularly when being inserted (installed) or removed (uninstalled). Referring to FIG. 14, connector 16 further includes a horizontal support member 110. Support member 110 extends between rear support member 44 and front support member 46. As shown, support member 110 is located approximately midway between upper track 40 and lower track 42. According to alternative embodiments, support member 110 may be at any of a variety of locations that provide desirable amount of structural support to connector 16. Support member 110 may be a formed channel (e.g., U-shaped, L-shaped, etc.), panel, plate, rod, tube, or the like.

Referring to FIG. 15, connector 16 further includes a vertical support member 112. Support member 112 extends between rear support member 44 and front support member 46. As shown, support member 112 is located approximately midway between rear support member 44 and front support member 46. According to alternative embodiments, support member 112 may be at any of a variety of locations that provide desirable amount of structural support to connector 16. Support member 112 may be a formed channel (e.g., U-shaped, L-shaped, etc.), panel, plate, rod, tube, or the like.

According to a preferred embodiment, top, panels, frame and connector are made of stainless steel. According to a particular preferred embodiment, the upper track, lower track, rear support member, and front support member are formed by a stamping and bending operation from a single sheet of metal. Alternatively, the connector and other components may be made from other metals or from polymers.
